How to use the Ready Player Me Avatar API for 2D profile pictures

To create 2D avatar profile pictures using the Ready Player Me avatar API, follow these steps:

  1. Generate a render request (you can paste the URL in you browser for testing):
    • Use a GET request to render 2D images of avatars. The base URL for rendering profile pictures is:

https://models.readyplayer.me/{avatar_id}.png

  • Customize the request URL with parameters such as blendShapes, cacheControl, quality, expression, pose, camera, size, and background to specify the look and style of the profile picture.
  1. Adjust render parameters for pictures:
    • blendShapes: map of 3D meshes to their blend shapes (?blendShapes[mouthSmile]=0.2). Read more on what are blendshapes.
    • quality: default quality is the highest. (?quality=0-100) Defines the compression quality for lossy formats like jpg.
    • expression: specify the facial expression the avatar will be making (?expression=happy/lol/sad/scared/rage).
    • pose: Set a static pose for the avatar (?pose=power-stance/relaxed/standing/thumbs-up).
    • camera: Define camera position to control the framing of the avatar (?camera=portrait/fullbody/fit). Portrait is the default camera.
    • size: specify image dimensions for width and height in pixels (?size=64/256/1024)
    • background: Choose a background color in RGB format (?background=144,89,156). The default is transparent.
  2. Integrate into your application:
    • Use the generated render URL in your app or platform to display dynamic profile pictures that can be personalized by users on the fly.

Examples:

You can combine multiple parameters by concatenating them with a “&”.

FAQ/Troubleshooting

1. Why is my avatar profile picture not appearing correctly?

  • Ensure that you are using the correct pose and camera parameters for the desired profile picture. Additionally, check if the background parameters are set properly to match your application’s requirements or if there are any spaces in the url.

2. How can I make avatar profile pictures more personalized for users?

  • The avatar API allows you to apply different poses and expressions to the avatars. You can build a simple photo booth experience to enable users to choose their pose and expression based on how are they feeling right now.

3. What image formats are supported for profile pictures?

  • The avatar API supports common formats like PNG and JPG.

4. How can I optimize the avatar images for better performance?

  • Adjust the resolution and output format to balance quality and performance. For example, using a lower resolution or JPG format can reduce file size and load times, which is beneficial for web and mobile applications.

5. Can I update avatar images in real time?

  • Yes, the avatar API is designed to support real-time updates. Simply change the parameters in the GET request to generate new images dynamically without the need to store them locally.
